4 Claims. 1

This invention relates to improvements in power sticks and sweep stickconnections and avoids the use of the conventional lug strap, providingfor longer wear, ease of adjustment, and other advantages.

Objects of the invention reside in the provision of an adjustable powerstick and holder therefor mounted on the picker stick stud shaft andpivoted to a sweepstick connection having rigid parts for longer use,the connection being reversible and useful at either side of the loomwithout change.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawing, in which Fig. 1 is aview in the side elevation of a form of the invention;

Fig. 2 is a section on line 2--2 of Fig. 1;

Fig. 3 is a top plan view of Fig. 1; and

Fig. 4 is a detail of a bumper.

In the drawing there is shown a conventional picker stick l mounted onthe stud shaft l2 in the usual manner. A holder comprising a metal plateI4 having side flanges l6 and a central slot IB is also mounted on thepicker stick stud shaft, and contains and supports between the flangesIS a power stick 2B. The latter is longitudinally adjustable in theholder by means of bolts 22 taking in slot I8.

At its upper end the power stick is provided with a pair of apertures 24for adjustably receiving a sleeve 26, the latter being longer than thethickness of the power stick and extending out from each side thereof.The sleeve spaces the power stick from a metal plate 28 and from anoffset strap 30 to allow for play between these parts. The offset strapand the plate 28 carry a bolt 32 passing through the sleeve to connectthe parts.

A second parallel metal plate 34 is secured in spaced relation to theplate 28 by a bolt 36 carrying between the plates a series of octagonalleather washers 38 acting as a bumper for the picker stick, although theinvention contemplates the use of bumper plate 4!] also. The washers 38may be rotated to present a plurality this plate.

of different bumping faces to the picker stick.

The bumper plate M1 is provided with recesses 4| receiving plates 28 and34 to detachably secure the bumper plate. The picker stick is locatedbetween the plates as indicated in Figs. 2 and PATENT OFFICE and theplates are adju'stably secured to the sweep stick 42 at their ends, andmount leather wear plates 44 at this point. The sweepstick is adjustablerelative to the plates 28, 34 by means of a bolt and slot connection 46.

The head 48 of bolt 32 keeps the picker stick generally out ofengagement with plate 28, there being a tendency for the picker stick torub on It will be clear that by removing the power stick, the holderplate, and plates 28 and 34 as a unit, the plates 28, 34 may be rotatedon sleeve 26 in a clockwise direction in Fig. 1 to extend in theopposite direction, so that the power stick may be used at either sideof the picker stick and either side of the loom. The arrangement shownand described outlasts the usual lug strap many times and keeps the loomin operation far longer.

Having thus described my invention and the advantages thereof, I do notwish to be limited to the details herein disclosed, otherwise than asset forth in the claims, but what I claim is:

1.- In a loom, a power stick comprising an elongated element, a pair ofspaced plates for connection to a sweep stick, a pivot'connection between one plate and the element, so that the 7 plates are completelyreversible relative to the element, and an oifset holder secured to saidone strap and embracing the power stick element, and a bumper spacingthe plates, a fastener thru the bumper, said fastener securing theholder to said one plate.

2. In a loom, a picker stick, a stud shaft, a power stick holder on thestud shaft, a power stick longitudinally adjustable in the holder, aplate, an offset element secured to the plate, a fastener extendingthrough the offset element, the power stick, and the plate and pivotingthe latter to the power stick, a second plate, the two plates containingthe picker stick, a bumper between the plates, said bumper beingrotatable to present a plurality of bumping faces to the picker stick,and

a sweep stick secured to the plates.

3. A m as recited in claim 2 including a detachable bumper plate for thebumper, and means on the bumper plate detachably securing th same to theaforementioned plates.

4. A loom as recited in claim 2 including means on the first plateprojecting into the space between the plates to insure the picker stickstriking the bumper centrally thereof.
